Silver’s question of the weekEdit
If you threw a crumpet off the top of the Empire State Building, would all the little holes help to slow its descent?Edit
There are two basic types of parachutes - lift-producing chutes and pure drag chutes. A crumpet is essentially the latter in miniature form. Similar to a traditional hemisphere-shaped chute, the crumpet would generate a vertical drag force that goes against the direction of travel. Drag is produced when the air below a descending object is forced around its sides or (in the case of the crumpet) into small air pockets. The combination of flour and yeast make the skin of a crumpet very porous and as air became trapped in its many holes, the crumpet would slow down.
If wind conditions were favourable and the crumpet was dropped holey-side down, then the bumpy bottom and smooth top of this chute would ensure gradual descent, with the textured surface creating sufficient friction to prevent the crumpet from speeding up. Most chutes are designed to carry something, but because of a crumpet's density it would not be able to support the weight of anything other than itself. To an onlooker it would appear that a small Frisbee or UFO was gliding gently to the earth.
Although crumpets tend to be very bland, if you are planning an experiment like this it is not advisable that you put butter or any other spread on the crumpet's surface. Not only will this increase the weight and decrease the number of holes available for air-trapping within the chute ; the cool wind pressure at high altitude could also cause the spread to harden or even spill, making it an unpleasant cake-munching experience for the hungry receiver waiting at the bottom of the building.
Next question: "Why do people throw tomatoes and eggs when surely coconuts would hurt more?"
I posted this early because I lack a proper schedule and to me every day is a Saturday and I thought today was Sunday, it turns out it wasn't, but at least it stops people stealing my news spot.
